MINING APPARATUS.

Original application filed March 3, 1919, Serial No. 28059 1. Divided and this application filed December My invention relates to mining apparatus.

An object of my invention is to provide an improved mining apparatus. Another object of my invention is to provide improved supplemental supporting means for a mining machine truck, and, more especially, such means adapted to use in unloading the mining machine on a bench or skids. A further object of my invention is to provide an improved mining apparatus of the general character described and claimed in my copending application Ser. No. 280,394, filed Mar. 8, 1919, of which this application is a division, having improved and simplified supplemental supporting means actuated in an improved and simplified manner. These and other objects and advantages of my improved construction will, however, hereinafter more fully appear.

In the accompanying drawings I have shown for purposes of illustration one form which my invention may assume in practice.

In these drawings,

-Fig. 1 is a side elevation of a mining apparatus equipped with my improvement, the parts being shown in transport position.

Fig. 2 is a fragmentary view of Fig- 1,

showing the parts in the position assumed during the process of unloading.

In this illustrative construction I have shown a mining machine truck, generally designated 1, having a longitudinally dis- I ose'l frame 2 mounted on and extendino' beyoud the front wheels of a set of truck wheels 3 which in turn are movable along a trackway t in a well. known manner. As in usual construction the truck wheels 3 are driven from a mining machine, generally designated 5, herein of the flexibly fed, room and pillar, endless cutter chain type and carried on the truck, a gear 6 on the rear end of the mining machine meshing, when the machine is in transportposition, with a gear 7 mounted on the rear end of the truck frame 2 and driving through mechanism (not shown) a transverse truck driving shaft 8 through chain and sprocket connections 9 and 10 with the truck wheels 3.

It will be observed that I have provided improved supplemental means for supporting the front end of the mining apparatus. as? shown these means engage directly with the mine bottom and are preferably so lo- Serial No. 679,213.

cated relative to the front end or" the truck frame 2 as thereby to provide a rigid support for the machine as the latter is moved longitudinally over the front end of the truck. More particularly, it; will further be noted that the supporting means are directly actuated and controlled by the mining ma-' chine 5 through an improved and simplified constr ction and arrangement of parts. Referring more particularly to the drawings it will be observed that a member 11, herein in the form of a laterally projecting pin extending from the side of the machine 5 and movable with the latter, engages with an upstanding cam member 12 of improved form pivotally mounted at 13 beneath the frame 2 in such manner as to swing the cam memher about its pivot and thereby operating a pivoted rod 14. As shown, the downward limit of movement of this rod is established by a stop member 15 and the front end of this rod is pivotally connected at 16 to the upper end of a supporting member 17 pivoted at 18 beneath the front end of the frame 2 and having its lower end engageable with the mine bottom at a point be tween the sides of the frame 2 and in front of the track. In the form illustrated here in, the cam member 12 is provided with a plurality of cam surfaces 19 and 20, of which the surface 19 is adapted to be disposed above the level of the frame 2 when the support 17 is in its inoperative position as shown in Fig. 1. Thus it will be observed that by providing a suitable trough or hollowed out portion 21 between these surfaces 19 and 20, it is possible to actuate this cam member to raise and lower the support 17 as the machine is loaded or unloaded. Preferably, the support 17 is also adapted'to use on the usual varying mine bottom by providing the same with a vertically adjustable portion'or foot 22 adapted to he held in ditl'erent posilions relative thereto by a suitable bolt 23 receivable in apertures 24 in the support 17. Obviously, in the use of this form of my invention, a like arrangement of parts may be, and is herein understood to be, provided on each side of the track In the operation of my improved mechanism it will be observed that it is possible to unload a room and pillar mining machine on a bench or on skids in a well known man ner without the necessity of jacking up the front end of the truck frame. In considering the operation of the mechanism let us remember that the machine in its movement about the mine occupies the transport position on the truck as shown in Fig. 1 and that the supporting means is in its inoperative position. The truck is, as usual, brought into a room or up to a bench under its own power and stopped with the front wheels thereof closely adjacent the front end of the mine track and with the front end of the truck f ame 2 extending beyond the end of the track in such manner as to bringthe machine as close as possible to the bench or the skids before it is unloaded. As the machine moved forward longitudinally of the truckframe 2, in any well known manner, and before the center of gravity of the machine passesover the front axle, the pin 11 on the machine engages the cam surface 19 on the cam member 12 thereby swinging the latter about its pivot 13 causing the rod to move forward and the support to swing down-- wardly engaging the bottom of the mine. Obviously after the machine has thus been provided with stable supportingmeans the machine is free to continue its forward movement, the machine sliding from the frame 2 onto the bench or skids. It is also obvious that when themachine is again loaded onto its truck the pin 11 will engage the cam surface 20 on the cam member 12 thereby raising the support 17 from the mine bottom.

\Vhile I, have in this application speeiti cally described one form which my invention may assume inpractice, it will be understood that this form oft-he same is shown for purposes of illustration and that the invention may be modified and embodied in various other forms withoutdeparting from.
